Question: What is axial flowers and terminal flower?

Axial and terminal flower refers to the position of the flower. Flowers located near the middle of the plant is axial whereas flowers located at the ends of the stems are terminal position.

What is terminal flowering?

The flower which grows at the tip of the plant is called as Terminal flower, whereas the flower which grows in stem regions other than tip of the plant is called as axial flower.

Are axial flowers recessive or dominant?

Thus, a purple flower in the axial position is a doubly dominant trait in pea plants, and a white flower in the terminal position is a doubly recessive trait.

What is solitary flower?

Solitary flower is one flower at a specific position of a plant. This flower appears singly or separated from other flowers by vegetative region. For example, Trillium grandiflorum.

What is the genotype for axial flowers?

(i) The phenotype of the F1 generation in plants with axial flowers will be produced. The genotype of F1 generation plants is Aa. (iii) From the above cross, 3 plants with axial flowers (Aa) and 1 plant with terminal flower (aa) is produced. So phenotypic ratio is 3 : 1.

What is axillary flower?

The axillary bud (or lateral bud) is an embryonic or organogenic shoot located in the axil of a leaf. Each bud has the potential to form shoots, and may be specialized in producing either vegetative shoots (stems and branches) or reproductive shoots (flowers).

What is mean by terminal and axillary?

The terminal bud arises from the tip of the stem and axillary buds arise from the leaf node of the stem. Hence both the terminal and axillary buds arise from the apex (apical meristem).

Which is a phenotype?

A phenotype is an individual’s observable traits, such as height, eye color, and blood type. The genetic contribution to the phenotype is called the genotype. Some traits are largely determined by the genotype, while other traits are largely determined by environmental factors.

What is the term genotype?

A genotype is an individual’s collection of genes. The term also can refer to the two alleles inherited for a particular gene. … The expression of the genotype contributes to the individual’s observable traits, called the phenotype.

What is the genotype of RR?

The (RR) genotype is homozygous dominant and the (rr) genotype is homozygous recessive for seed shape. In the image above, a monohybrid cross is performed between plants that are heterozygous for round seed shape.

What is terminal inflorescence?

An inflorescence that arises from the end of a stem, as apposed to an axillary inflorescence that arises from the axil (leaf base)

What is umbel inflorescence?

In botany, an umbel is an inflorescence that consists of a number of short flower stalks (called pedicels) which spread from a common point, somewhat like umbrella ribs. The word was coined in botanical usage in the 1590s, from Latin umbella “parasol, sunshade”. … An umbel is a type of indeterminate inflorescence.

What is sessile flower?

In botany, sessility (meaning “sitting”, used in the sense of “resting on the surface”) is a characteristic of plant parts (such as flowers and leaves) that have no stalk. … A sessile flower is one that lacks a pedicel (flower stalk).

Is PP genotype or phenotype?

There are three available genotypes, PP (homozygous dominant ), Pp (heterozygous), and pp (homozygous recessive). All three have different genotypes but the first two have the same phenotype (purple) as distinct from the third (white).

What are the heterozygous genotypes?

An organism with one dominant allele and one recessive allele is said to have a heterozygous genotype. In our example, this genotype is written Bb. Finally, the genotype of an organism with two recessive alleles is called homozygous recessive. In the eye color example, this genotype is written bb.

What is a genotypic ratio example?

It describes the number of times a genotype would appear in the offspring after a test cross. For example, a test cross between two organisms with the same genotype, Rr, for a heterozygous dominant trait will result in offspring with genotypes: RR, Rr, and rr. In this example, the predicted genotypic ratio is 1:2:1.
